SUBSTANCE: injector is designed for supply of plastic lubricant under pressure via lubricating screws into lubricated units of motor transport, agricultural and other machines during their maintenance and repair. An injector comprises a jack, which is equipped with a spring energy accumulator for supply of lubricant under pressure. The energy accumulator is equipped with a cylinder for lubrication with a piston arranged in it and a compression spring above it, and also pressing and support discs with the compressing spring between them, bolts, which stiffly fix the support disc with a support, and a cylinder cover.
